Apparently some female Australian bloggers, a feminist organization, some random "empowered" Amerocan teenager, well, all of them generally English-speaking and not Asians.
I think, having Japanese as a prop is meaningless. It doesn't mean our culture being appropriated by a domineering civilization, or some twisted minds of theirs like that. What I see is an enthusiasts white girl trying to embrace it but just fail. I know K-pop and J-pop, and this video is exactly like that, because it is made by a Japanese in Japan, by a Japanese recordingcompany.
Perhaps these guurrrrls think too much about their weird guilty pleasure fantasy with foreign cultures, like Anna and the King, The Sheik, Tarzan and Jane, etc.
